Title: Automatic interlining and leading apparatus for type setting and casting machines
IPC: B41B3/06
Filed: 1922-04-13
Abstract: 197,168. Garda, E. April 13, 1922. Type bar - making machines; leading-mechanism for single type composing and casting machines. In a device for leading or interlining matter produced by singletype composing and casting machines, space-lines or leads extracted from a magazine by means of a pincer-like device are inserted between successive lines of matter in the galley, and the space-lines are coated on one face with adhesive to cause them to adhere to the types of the previouslv cast line. Two or more space-lines may be inserted at each operation of the device, and the space-lines may be in sections for tabular composition. The types are preferably formed with a recess 1, Fig. 2, adapted to receive a space line 2. The space-lines are contained in a magazine 6, Fig. 7, in which they are supported on plates 8, Fig. 9, and are retained by adjustable blades 10 beneath which is a passage for the extraction of the space-lines. One or more. adjustable partitions 10<a> are employed when the space-lines are in sections. The space-lines are extracted from the magazine and delivered to the galley 15 by a pincer-device formed by arms 26, 27 carried by a lever 22, the shaft 20 of which is oscillated by a toothed segment 19 and a rack 18 from the galley-mechanism. The arms 26, 27 have a pivotal and a limited sliding movement on the lever 22, and are spring-controlled so that, when the lever rises, the lowest space-line in the magazine is gripped between adjustable member 37 on the arms 27 and adjustable springs 36 on the arms 26. On the descent of the lever, the arms 26 are retracted by a fixed arm 57, which also rocks the arms 27 so that the space-line is released and falls into the space between the walls of the double rule 59 at the entrance to the galley. When the rule rises to permit the following line 66 to be pushed into the galley by the pusher 65, the space-line is moved into engagement with the recesses in the previous line 64. The coating of the space-lines with adhesive is effected during their extraction from the magazine by a segment 41, which is geared to a supply-roller 42 and is oscillated by a toothed segment 45 carried by an arm 46 which receives a limited rocking movement from the shaft 20. The space-lines are correctly positioned in the galley by a plate 60, Fig. 13, which is supported by pins 62 and an inclined slot 61 from the rule 59 so as to push the space-line endwise as the rule rises.

Title: Improved process for cooling viscous liquids and apparatus therefor
IPC: F28D3/02
Filed: 1920-04-19
Abstract: 142,454. Soc. de Condenseurs Delas. April 30, 1919, [Convention date]. Tube-plates.-Viscous liquids, such as oils, are allowed to fall in separate drops over the surfaces of superposed internally-cooled tubes so that the drops spread in a short film over each tube and then reform independently and fall to the next tube. The apparatus comprises a series of tubes A enclosed in a casing to exclude dust, and a series of spaced nozzles B through which the oil is distributed. The cooling water flows through the tubes in a sinuous path from the bottom to the top. In the case of lubricating oil for electrical apparatus where it is important to prevent the entrance of water into the oil, the water boxes or headers D may be separated by a space from the end tube plates F of the oil chamber. In addition to this, the oil chamber may communicate with a chamber containing an hygroscopic substance. To minimize the danger of water leakage, the water may circulate under reduced pressure.
Patent GB-446222-A (GB)
Title: Improvements in the manufacture and production of halogenated ethers
Filed: 1935-04-09
Abstract: Halogenated ethers are obtained by reacting a halide of the general formula <FORM:0446222/IV/1> (in which R represents hydrogen, alkyl, aralkyl or aryl, R<1> represents alkyl, aralkyl, or aryl and X represents halogen) with compounds having conjugated olefinic double bonds.  An anhydrous metal halide, e.g. zinc or mercury chloride, may be employed as a catalyst.  Suitable halides include a -chlordimethylether, a -chlordiethylether, a -chlormethyldodecylether, a -chlor - didodecylether, a  - methoxybenzylchloride and its derivatives substituted in the benzene nucleus and a -chlorcinnamic ethyl ether or the corresponding brominated products.  Examples of compounds having conjugated olefinic double bonds are butadiene, its homologues such as isoprene, and dihydrobenzene.  The reaction may be conducted in a solvent such as benzene or acetylene tetrachloride.  According to examples: (1) 1-phenyl-1-methoxy - 5 - chlor - pentene - 3 is obtained by reacting butadiene with a -methoxy-benzylchloride in a pressure tight vessel in the presence of mercuric chloride, the crude product being shaken with aqueous sodium chloride and extracted with ether; (2) 1-methoxy-5-chlorpentene- 3 is obtained by reacting butadiene with a -mono-chlor dimethyl ether in the presence of mercuric chloride in a pressure-tight vessel at 30 DEG  C., the product being isolated as described in example (1); (3) 1-phenyl-1-methoxy-5-brompentene-3 is obtained by reacting butadiene with a -methoxy-benzylbromide in the absence of a catalyst; (4) methoxy-benzyl-chlor-cyclohexene of unknown structural formula is obtained by reacting 1-2-dihydrobenzene with a -methoxy-benzyl chloride in the presence of mercuric chloride; methoxy-methyl-chlor-cyclohexene is obtained by reacting 1-2-dihydrobenzene with a -monochlordimethyl ether in the presence of mercuric chloride.  Specification 423,520 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the replacement of the halides in the above reaction by mixtures of aldehydes with alcohols and halogen hydrides; mixtures of para-formaldehyde with methanol and hydrogen chloride, mixtures of acetaldehyde with ethanol and hydrogen chloride, mixtures of formaldehyde with dodecyl alcohol and hydrogen chloride, and mixtures of benzaldehyde with methanol and hydrogen chloride being specified. Other olefinic compounds not containing conjugated double bonds, e.g. trimethylethylene and cyclohexene can also be employed.  This subject-matter does not appear in the Specification as accepted.
Patent GB-668276-A (GB)
Title: Improvements in gas-blast electric circuit-breakers
IPC: H01H39/00
Filed: 1948-04-20
Abstract: 668,276. Gas-blast switches. WHITNEY, W. B., BRISCOE, E. M., HUDSON, A. A., and BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION. April 11, 1949. [April 20, 1948] No. 10930/48. Class 38 (v). In a gas-blast switch, the blast pressure is obtained from the gases discharged from an explosive or other gas emitting cartridge into the switch container, the arrangement being such that the relatively cool air or gas in the container is initially driven against the arc for a period of at least one cycle from the commencement of the arc. The container has three parts ; a tank 12 into which the cartridge 40 discharges when a firing pin 48 is struck by a hammer 47 ; an intermediate chamber 13 housing the switch operating mechanism ; and a switch chamber 14 in which a moving contact 17 co-operates with a fixed nozzle contact 15. The three parts of the container are separated by filters 44, 45 of expanded metal or perforated metal plates, and the resin bonded paper wall 19 of the switch chamber 14 may have a quartz lining 20. When the cartridge is fired, the gases are directed by a nozzle 43 on to the end wall of the tank 12 so as to reduce the kinetic energy of solid particles in the gases. The gases then pass through the filter 44 into the chamber 13 and then through the filter 45 into the chamber 14. The pressure in the chamber 13 forces down a piston 26 against the pressure of a spring 28, to retract the contact 17. A blast of air, which is followed by the blast of the cooled and filtered gases, flows from the chamber 14 through the nozzle contact 15 to extinguish the arc drawn between the contacts. The downward movement of the contact 17 is limited by the engagement of a collar 30 on the piston rod 29 with the spring loaded piston 31 of a dash pot 32. As soon as the pressure in the chamber 13 falls, the spring 28 returns the piston 26 to reclose the contacts 15, 17, but in the meantime an isolating switch 138 will have been opened. The contact 17 has a lip 18, and the contact 15 an insert 56, of highly refractory metal such as a sintered tungstencopper mixture. A single cartridge and tank may be used for all three phases of a three phase switch. The insertion of a fresh cartridge may be effected manually or by an automatic cartridge feed. The tank 12 may be of large thermal capacity, or have cooling fins or be cooled by water. Specifications 26694/01, [Class 38], and 278,764, [Class 38 (v)], are referred to.

Filed: 1960-03-29
Abstract: In a horizontal beam dyeing machine of the type in which cloth is rolled on a perforated <PICT:0903525/IV (b)/1> <PICT:0903525/IV (b)/2> stainless steel beam which is lowered into a tank or vat, the beam is mounted horizontally in the vat and an impeller or rotor is mounted in an end cover forming a housing therefor to circulate liquor from the vat into the interior of the beam and out through the perforations and the fabric thereon.  As shown, a perforated dye beam 1 is constructed to fit into end cover 2 housing an impeller or rotor 3 mounted on spindle 4 driven by an electric motor.  The opposite end of beam 1 is closed by an end wall 16 through which passes a screwed rod 17 on which is mounted a disc 18 which can thus be adjusted longitudinally of the beam for various width materials.  Cloth is wound on the beam 1 which is then lowered into vat 6 containing dye liquor and a heat exchange panel 23.  The beam may be mounted in V supports or in bearings so it can rotate slowly due to the action of the liquid impinging on it.  The liquor is circulated in a closed circuit in the vat 6 by the impeller 3, passing from the interior of the beam through the cloth and back into the vat.  A supply of dye is contained in reservoir 6b and below this is mounted a chamber 6c which houses a small perforated cylinder on which a sample piece of material is wound.  Dye liquor is circulated from the inside of end cover 2 through pipe 6a to chamber 6c and back through a return pipe to vat 6 so that a sample beam dyeing machine is produced which duplicates the conditions inside the main machine and from which test pieces of dyed fabric can be taken.

Title: Improvements in and relating to the production of dihydric phenols
Inventor: BERNEIS KURT HELMUT
IPC: C07C39/08
Filed: 1954-04-15
Abstract: Dihydric phenols are prepared by decomposing meta- or para-dialkyl benzene dihydroperoxides which are solid at 15 DEG  C. or more, by adding sulphuric acid or a solution of sulphuric acid in an inert organic solvent which is also a solvent for the dihydroperoxide to a solution of the dihydroperoxide in the same inert organic solvent, the concentration of the acid by weight being up to 3 per cent of the weight of the reaction mixture and the temperature being maintained at from 0 DEG  C. to the boiling point of the reaction mixture.  The solvent may be the ketone identical with that liberated during the reaction or the monohydric alcohol corresponding to it and may contain up to 20 per cent by weight of the dihydroperoxide.  Water is substantially absent from the reaction mixture which is stirred throughout.  Concentrated sulphuric acid of s.g. 1.84 may be used in amounts varying from 0.1 per cent to 0.5 per cent by weight of the reaction mixture and may be dissolved in about 10 per cent of the total inert organic solvent used.  The reaction is carried out preferably between 15 DEG  and 30 DEG  C., under an inert gaseous atmosphere which may be nitrogen or carbon dioxide.  The phenols produced are isolated by neutralizing the reaction mixture with solid sodium carbonate, filtering and evaporating the solvent in the presence of marble chips and distilling under an inert atmosphere at ordinary pressure by heating, or under reduced pressure at room temperature.  In examples (1) p-di-isopropyl benzene dihydroperoxide in acetone is decomposed with sulphuric acid either alone or in acetone solution under varying conditions of concentration and reaction time, the hydroquinone being isolated as described above under reduced pressure and a carbon dioxide atmosphere; (2) sulphuric acid in isopropanol is added to p-di-isopropyl benzene dihydroperoxide in isopropanol at room temperature, the temperature being raised after addition, the mixture treated with solid sodium carbonate, filtered and evaporated to dryness under reduced pressure with marble chips and under carbon dioxide to give hydroquinone which is recovered by sublimation; (3) sulphuric acid in acetone is added to a mixture of m- and p-di-isopropyl benzene dihydroperoxides in acetone at room temperature, the temperature raised after addition and the mixed dihydric phenols isolated as described in (2). Specification 684,039 is referred to.
